Abstract: In connection with analyses of severe air ingress accidents in high temperature gas-cooled reactors, in a previous work /I/ kinetic data on the reaction between oxygen and graphitic fuel element matrix materials in the inpore diffusion controlled regime have been presented. Supplementary to this the present report in the same field of parameters such as temperatures (approx. 950-1200 K $\triangleq$ approx. 680-930 ° C), gas pressure (1,5 bar constant with helium as the carrier gas) and oxygen partial pressures (0,015 to 0,15 bar) deals with the kinetics of the reaction of the graphites ASR-1RS, ASR-1RG, V483T and ATR-2E with oxygen. As a result these graphites - also in comparison with the matrix materials - show comparatively small differences in their reactivities with ASR-1RS having the lowest, ATR-2E the highest reactivity. The experiments in oxygen containing helium hereby have been completed.
